Abstract

The invention provides a battery cap welding machine, comprising: a frame, on which are provided a pole piece device, a tab correction device, a cap rotation device, a welding telescopic device, a tensile testing device, and a cap cap tab shaping device, The cap rotating device and the welding telescopic device are arranged oppositely, the pole piece device is set at one end of the cap rotating device, the tab correction device is set at the end of the welding telescopic device close to the pole piece device, and the tensile test device is set at the other end of the welding telescopic device , the gland cap lug shaping device is set parallel to the tensile testing device. The electrode piece device pulls up the pole piece on the cap, and the tab correction device rotates the tab on the battery case to align with the pole piece. The battery case and the cap are placed on the welding telescopic device and the cap rotating device to align and weld, and the welded battery is in the The tensile test device is used to test the welding strength, and the tab cap tab shaping device is used to complete the shaping of the tab and the compression of the cap, realizing automatic welding and greatly improving production efficiency.

Description

technical field [0001] The invention relates to the technical field of battery production, in particular to a battery cap welding machine. Background technique [0002] During the battery production process, the battery cells need to be put into the battery case, and then the pole piece on the cap is welded to the tab on the battery cell. After welding, the cap is fastened on the battery case to make the battery sealed. In order to facilitate the welding of the pole piece, it is necessary to lift the pole piece from the cap, and rotate the pole lug and the cap to the corresponding positions respectively, so that the pole lug and the pole piece are aligned for welding. The welding strength of the pole piece is tested to reduce the defective rate. However, if the above-mentioned series of processes are completed manually, the efficiency is low, and it will consume a lot of labor costs and time, resulting in high production costs; on the other hand, resulting in a high defect ...
